Red blood starting again 2 days after period ended

I’m in my 30s and this has never happened to me. Got my period on a Wednesday, by Monday it was almost done just the usual brown spotting and same for Tuesday. Now it’s the following Wednesday and my uterus has the full feeling, is crampy and I’m bright red bleeding again and quite a bit. What the heck? Anyone have this happen and not have fibroids or something
